In a dice, the total even numbers (2,4,6)= 3
Therefore, the probability that she will roll an even number will be given by:-

Answer
According to newton law of cooling
and
now At Ta = 100
T₀ = 10 °C
T₁ = 12° C
10 = C + 100
C = -90
now,
at time equal to t
T(t) = 70
t = 48.88 s
hence, after 48.88 s the temperature of the body will be 70°C
b) time taken to reach 98°C
t = 390 s
hence, after 390 s the temperature of the body will be 98°C
